The design, called "Technology," will be coming to the new Z-2 NASA suit this fall.

The suit features electroluminescent wire and patches across the upper and lower body.

From NASA:

"Technology" pays homage to spacesuit achievements of the past while incorporating subtle elements of the future. By using Luminex wire and light-emitting patches, this design puts a new spin on spacewalking standards such as ways to identify crew members.

For all this trouble, the Z-2 won't make it to space - it's earthbound!

The cover layer of a non-flight suit, which is used for ground-based testing, serves as abrasion/snag protection, a cover for technical details, and to a lesser extent, aesthetics. For a flight suit which is actually used for a spacewalk, the cover layer performs many other important functions such as micrometeorite, thermal and radiation protection. These requirements drive selection of specific high-performance materials and design details that would preclude us from using many of the features you see in these options for the Z-2 suit.
